哎，花班真有知识，“儒艮”这两个字我一看到傻眼了，不知道怎么读...

我查了一下，儒艮的英文是dugong, 我也是不认识。问了AI，它们基本是差不多的动物，就是尾巴略有不同，我又学习了。

"Manatees and dugongs are related to each other and while they are very similar in appearance and behavior, there is one key difference – their tails. Manatees have paddle-shaped tails and dugongs have fluked tails, giving it a whale-like appearance."
